The present disclosure provides an electronic cigarette 1000.

Referring to FIG. 1 to FIG. 5, the electronic cigarette 1000 of the present disclosure includes an atomizer 100 and a power supply assembly 200. The power supply assembly 200 is internally provided with a master control board 220 which is in electrical connection with an inbuilt power supply 210. The atomizer 100 includes a top cover 10, a base 30, an atomizing assembly 50, and a light-transmitting sleeve 70 connecting the top cover 10 and the base 30. The atomizing assembly 50 is accommodated in the light-transmitting sleeve 70, and a liquid storage chamber 60 is defined between the atomizing assembly 50 and the light-transmitting sleeve 70. The atomizing assembly 50 defines an atomizing chamber therein, and the atomizing assembly 50 has one end far away from the top cover 10 defining at least one liquid guide port 52 which is in communication with the liquid storage chamber 60.

The top cover 10 includes a cover body 11, a mouthpiece 12 and an aerosol outlet pipe 13. The cover body 11 defines a liquid refill hole 1111 which is in communication with the liquid storage chamber 60 and an air inlet chamber 1112 which is in communication with the atomizing chamber. The aerosol outlet pipe 13 is at least partially accommodated in the air inlet chamber 1112, and the aerosol outlet pipe 13 has two ends communicated with the mouthpiece 12 and the atomizing chamber respectively. Exterior air passes through the air inlet chamber 1112, the atomizing chamber and the aerosol outlet pipe 13 in sequence and finally is expelled from the mouthpiece 12.

The base 30 includes a base body 31, an electrode assembly 32, and a light-emitting assembly 33 illuminating the liquid storage chamber 60. The base body 31 is fixedly mounted on the power supply assembly 200, the electrode assembly 32 electrically connects the atomizing assembly 50 to the master control board 220, and the light-emitting assembly 33 is fixedly mounted on the base body 31 and is electrically connected to the master control board 220.

According to the electronic cigarette 10000 provided in the technical scheme of the present disclosure, the top cover 10 defines the liquid refill hole 1111 and is provided with the mouthpiece 12 and the aerosol outlet pipe 13 which is in communication with the mouthpiece 12, wherein the liquid refill hole 1111 is in communication with the liquid storage chamber 60, the aerosol outlet pipe 13 is in communication with the atomizing assembly 50; meanwhile, the atomizing assembly 50 defines the liquid guide port 52, so that the atomizing chamber is in communication with the liquid storage chamber 60. Therefore, a tobacco liquid enters the liquid storage chamber 60 from the liquid refill hole 1111 defined on the top cover 10, and then permeates into the atomizing chamber from the liquid guide port 52 defined at the bottom of the liquid storage chamber 60. Exterior air enters the atomizing chamber through the air inlet chamber 1112 defined on the top cover 10, and then flows out through the mouthpiece 12, mixing with an atomized aerosol, for a user to inhale. The tobacco liquid in the liquid storage chamber 60 is not easy to leak through the air inlet chamber 1112 defined on the top cover 10 of the electronic cigarette 1000. Therefore, the sealing performance for the tobacco liquid is improved. Meanwhile, the aerosol outlet pipe 13 is partially accommodated in the air inlet chamber 1112. When a user inhales, exterior cold air enters the air inlet chamber 1112 and then contacts the aerosol outlet pipe 13 accommodated in the air inlet chamber 1112 to be preheated, and then flows into the atomizing chamber for the tobacco liquid to be atomized to form a hot air aerosol, and finally is expelled through the aerosol outlet pipe 13. At such time, when the hot air aerosol flows through the aerosol outlet pipe 13 accommodated in the air inlet chamber 1112, the hot air aerosol exchanges heat with cold air to cool down. Therefore, the condition the hot air makes the mouthpiece 12 hot to burn mouth is effectively avoided. Moreover, the present disclosure illuminates the liquid storage chamber 60 by arranging the light-emitting assembly 33 on the base body 31. Various lighting effects can be generated during the usage process of the user. The use experience of the user is effectively improved.

Here, in the present embodiment, the mouthpiece 12 is partially accommodated in the accommodation hole, and the mouthpiece 12 is provided with threads and is fixedly connected to the moveable cover 112, so that a user can replace the mouthpiece conveniently. Meanwhile, occurrences of the mouthpiece 12 falling off and getting lost can be effectively avoided. Further, the moveable cover 112 and the fixed cover 111 are connected through a rotating pin. The rotating pin may have one end fixedly connected to the fixed cover 111 through interference fit and the other end connected to the moveable cover 112 through clearance fit, so that the moveable cover 112 is capable of rotating. The connection pin is capable of extending out the moveable cover 112. The portion of the rotating pin extending out the moveable cover 112 may be provided with a stop block or an adjusting nut, so that the moveable cover 112 is not easy to separate from the fixed cover 111.

Further, as shown in FIG. 1 to FIG. 4, in the embodiment of the present disclosure, a sealing pad 113 is further provided between the fixed cover 111 and the moveable cover 112, the fixed cover 111 defines an accommodation recess 1113 configured for accommodating the sealing pad 113, the liquid refill hole 1111 is defined in the accommodation recess 1113, the sealing pad 113 defines an opening (not marked in the drawings) corresponding to the liquid refill hole 1111, the moveable cover 112 abuts against the sealing pad 113 when covering the liquid refill hole 1111. In addition, in the present embodiment, the sealing pad 113 is made of elastic rubber materials. The elastic effect of the sealing pad 113 enables a sealing cover and an upper cover to keep an interaction force against each other, thus the sealing cover and the upper cover are not easy to loosen after they abut against each other. Meanwhile, one surface of the sealing pad 113 facing the moveable cover 112 is provided with a rib surrounding the liquid refill hole 1111, so that, when the moveable cover 112 covers the accommodation recess 1113, the moveable cover 112 is in interference fit with the rib to tightly abut against the sealing pad 113 and to tightly seal the liquid refill hole 1111. And/or, one of the fixed cover 111 and the moveable cover 112 defines a snap-in connection groove 1122, and the other one of the fixed cover 111 and the moveable cover 112 is provided with a snap-in projection 1114; when the snap-in projection 1114 and the snap-in connection groove 1122 are in a snap-fit connection, the moveable cover 112 is tightly locked in the fixed cover 111 and covers the liquid refill hole 1111. Here, in the present embodiment, when the moveable cover 112 is fastened in the fixed cover 111 through a snap-fit connection, loosening is not easy to occur.

Further, as shown in FIG. 1 to FIG. 3, in the embodiment of the present disclosure, the top cover 10 further includes a regulating ring 14, the regulating ring 14 is sleeved on the periphery of the fixed cover 111 in a rotatable manner, and the regulating ring 14 has a side wall defining a regulating hole 141 corresponding to the air inlet chamber 1112. Here, the regulating ring 14 can be sleeved on the fixed cover 111 through thread or clearance and the like structure. The side wall can define a plurality of regulating holes 141 simultaneously. When the regulating ring 14 moves by rotation on the periphery of the fixed cover 111, overlapping of opening areas is caused between the regulating hole 141 and the air inlet chamber 1112, and air enters from the overlapped opening area, thereby regulating the amount of air input. Since the amount of air input directly influences the volatile effect of the tobacco liquid, rotating the regulating hole 141 can control the volatile speed of the tobacco liquid, thereby satisfying the use experiences of different users.

Further, as shown in FIG. 1, FIG. 3 or FIG. 4, in the embodiment of the present disclosure, the periphery of the moveable cover 112 is provided with a plurality of bumps which are arranged spaced apart. Here, in the present embodiment, by providing on the periphery of the moveable cover 112 a plurality of bumps which are arranged spaced apart, when a user rotates the moveable cover 112, the friction is effectively enhanced, the occurrence of slipping is avoided and it is convenient for the user to operate. And/or, the periphery of the regulating ring 14 is provided with a plurality of projections 142 which are arranged spaced apart. Here, in the present embodiment, by providing on the periphery of the regulating ring 14 a plurality of projections 142 which are arranged spaced apart, when a user rotates the regulating ring 14, the friction is effectively enhanced, the occurrence of slipping is avoided and it is convenient for the user to operate.

It is understandable that, during practical applications, the manner of enhancing the friction between the moveable cover 112 or the regulating ring 14 and a human body is not restricted to the above manner of providing a plurality of projections 142 or bumps, for example, it can also apply the manner of providing irregular patterns on the peripheries of the moveable cover 112 and the regulating ring 14 and other manners of enhancing friction, which are all intended to be included in the scope of protection of the present disclosure.

Further, as shown in FIG. 2 or FIG. 3, in the embodiment of the present disclosure, a connection ring 15 is further provided between the top cover 10 and the atomizing assembly 50, and the connection ring 15 has one end sleeved on an outer wall of the air inlet chamber 1112 and has the other end connected to the atomizing assembly 50 through thread. Here, in the present embodiment, one end of the connection ring 15 is sleeved on the periphery of the chamber wall of the air inlet chamber 1112, and the other end thereof is connected to the atomizing assembly 50 through thread, meanwhile, the base 30 and the atomizing assembly 50 are in thread connection, thus the atomizing assembly 50 is convenient to disassemble or assemble. Herein, the air generated when the tobacco liquid in the atomizing chamber is atomized passes through the aerosol outlet pipe 113 penetrating into the air inlet chamber 1112, and then reaches the mouthpiece 12. A user inhales the aerosol through the mouthpiece 12. Exterior air enters the atomization chamber after entering the air inlet chamber 1112 via the regulating hole 141, so that the atomized air in the atomization chamber is not easy to volatile out from the air inlet chamber 1112. The utilization and use effect of the tobacco liquid are improved. Moreover, air can be temporarily stored through the air inlet chamber 1112 and the normal volatilization of the tobacco liquid is guaranteed.
